Preston Way in Mount Kisco was closed Wednesday afternoon for an acid spill on the road, according to fire officials.
Passers-by called police about 12:15 p.m., said Mount Kisco fire Chief Tom Jackson. Apparently a small container fell from a vehicle and spilled—and the liquid from the container began smoking as it came in contact with the roadbed and the rain.
The road was spotted as having been reopened shortly before 2:30 p.m.
Firefighters and the Westchester County HazMat team have contained the spill, which had gotten into the storm drain.
"There is no hazard to life or limb," Jackson said.
Jackson said the department is awaiting the county Health Department, which must OK the final clean-up and disposal efforts. After that, the road can be re-opened, he said.
Preston abuts a large shopping plaza to the north, which includes Target and A&P.
